Something I always thought about art is that everyone interprets it differently, neither being right or wrong necessarily, just different for each individual. This being said, for all of the great examples you provided, I felt very similar. I enjoyed the way you described the "warmth" of their family given the colors the author/artist utilized. The art truly did envoke real, deeper feelings, something I never expected to result from a biography of a scientist that lived over 100 years ago
